YPSILANTI, MICHIGAN SHADE ROLLER Application filed. June 23,

The present invention relates generally to shade rollers, and aims toprovide a construction which is more positive and uniform in action thanthose in present day use.

In carrying out the invention, we provide a novel construction of means,including a sliding pawl, which is positive in operation to check slowrotation of the roller, and yet permit fast rotation of the roller, sothat under the influence of its spring, the roller can berotated in theproper direction to raise or elevate the shade.

Another object of the invention resides in the manner of mounting thespring of the I roller, to provide for both simplicity and rigidity inthe construction, and to protect the spring and its associated partsfrom dust and other foreign matter.

The nature and advantages of the invention will be better understoodwhen the following detail description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals ofreference indicate similar parts in the several views and where- Figure1 is a view in elevation and partly in section.

Figure 9 is a similar view ofthe bearing for the ratchet member.

Figure 10 is a fragmentary longitudinal section of a wooden roller.

Figure 11 is an enlarged elevation of the rod supporting disk shown inFigure 10.

Referring to the drawings in detail, 10 represents a hollow shaderoller, preferably formed from metal and having its edges joinedtogether by a suitable lock seam 11 disposed within the roller as shown.The opposed ends of the roller are closed by flanged caps 12 and 13respectively, the former supporting the usual pintle 14 while the latterhas a circular opening 15 for a purpose 50 to be hereinafter described.

Arranged centrally within the roller 10 is a stationary hollow rod 16,supported at one end by a disk 17 having a boss 18 projecting therefromand rotatably received by the adjacent end of the rod 16. The disk 17 isnotched as at 19 to receive the lock seam 11 of the roller, by reasonofwhich construction the disk is rotated with the roller as will bereadily understood. Stamped from this 7 disk 17 are tongues 20 to whichthe coil spring 21 is attached. 7 One end of the spring'is slipped overone of the tongues as shown in Figure 5, while the adjacent convolutionof the spring is positioned between the disk and tongues as illustratedin Figure 6. The opposite end of the rod is provided with opposedlongitudinal slots 22 and 23, the latter being relatively short andopening at one end of the rod.

A flat bracket arm 24 is received by the hollow rod 16, and formed withan oflset intermediate portion 25 which projects through the slot 22- ofthe rod, and provided with an opening 26 through which the adjacent endof 55 the spring is passed and secured to said arm. Depending from thelower edge of the bracket arm is a lug 27 received by the slot 23. Theouter end of the bracket arm projects beyond the adjacent end of theroller, and

passes through the opening of the cap 13. This end of the bracket armtogether with the pintle 14 serves to support the roller on window shadebrackets of ordinary well known construction. Also projecting from theopposed longitudinal eges of the arm are lugs 28 disposed within theroller inwardly of the cap 13.

Supported on the bracket arm and located at opposite sides of the lugs28 between the latter and the adjacent end of the rod 16 and theadjacent cap 13 are bearing disks 29, each having a slot 30 to receivethe bracket arm as shown. These bearings disks are each formed with areduced portion forming an annular bearing surface 31, and

this portion of the outer disk is journaled in the opening 15 of cap 13.A ratchet-like member 32 is j ournaled on the inner disk 29, and thismember 32 is in the nature of a cap having a central opening toaccommodate the bearing surface 31 of said inner disk as shown in Figure2. Carried by the cap 32 1s a flange 33 secured in any suitable mannerto the adjacent end of the roller 10. Consequently the ratchet member 32rotates with the roller and about the bearing surface 31. The ratchetmember 32 is provided with opposed openings 34 to cooperate with asliding pawl 35. This pawl is slotted as at 36 to receive the bracketarm, and the slot is of a length to accommodate the lugs 28 thereon.

The pawl is formed with diametrically opposed projections 37 adapted tobe alternately received by the openings 34, and it is by reason of thisconstruction that the roller can be positively checked while beingslowly rotated, and at the same time, permit the roller to be morerapidly rotated without any interference by the pawl. Manifestly, theaction of the pawl is not only positive, but uniform, while the springis rigidly mounted and protected from dust and other foreign matter,together with its associated parts. I

The present winding unit can be used with wooden rollers as illustratedin Figures 10 and 11. As shown, the wooden roller, 1005 has an axialbore 40 at one end to receive the hollow rod 16a and spring 21a, the rod16a being supported by "a disk 17a having prongs 41 adapted to be driveninto the roller at the inner end of said bore. Otherwise, theconstruction of the winding unit will be the same for both metal andwooden rollers.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily understood, we desire tohave it known that we do not limit ourselves to what is hereinillustratedor described, and that such changes may be resorted to whendesired as fall within the scope of what is claimed.

What we claim asnew is: 1. A hollow spring wound shade roller, a hollowstationary rod arranged centrally therein and having a longitudinalslot, a disk mounted on one end of said rod and rotated with saidroller, a bracket arm received by said rod and projecting beyond theadjacent end of the roller, said arm including an offset intermediateportion projecting through the slot in said rod, a spring encirclingsaid rod and having its ends connected with the offset portion of thearm and disk respectively, and pawl and ratchet means for the roller.

2. A hollow spring wound shade roller, a hollow centrally locatedstationary rod therein having a longitudinal slot, a disk mounted on oneend of the rod and rotated with said roller, a bracket arm received byend of the roller, said arm including an offset intermediate portionprojecting through said slot, a spring encircling said rod and havingits ends connected with the ofiset portion of the arm and diskrespectively, and a pawl and ratchet means supported by said arm andwithin said roller.

3. A hollow spring wound shade roller, a hollow centrally locatedstationary rod therein having a longitudinal slot, a disk mounted on oneend of the rod and rotated with said roller, abracket arm received bysaid rod and projecting beyond the adjacent end of the roller, said armincluding an offset intermediate portion projecting through said slot, aspring encircling said rod and having its ends connected with the offsetportion of the arm and'disk respectively, a ratchet member mounted forrotation with the roller and about said arm, and a cooperating pawlslidably supported on said arm.

4. A hollow spring wound shade roller, a hollow centrally locatedstationary rod therein having a longitudinal slot, a disk mounted on oneend of the rod and rotated with said roller, a bracket arm received bysaid rod and projecting beyond the adjacent end of the roller, said armincluding an offset intermediate portion projecting through said slot, aspring encircling said rod and having its ends connected with the otfsetportion of the arm and disk respectively, a slotted disk-like bearingsupported on said arm,

a ratchet member carried by the roller and rotatable on said bearing,and a sliding pawl suported on the arm and cooperating with saidratchet.

5. A hollow spring wound shade roller, a. hollow centrally locatedstationary rod there-" arm and disk respectively, lugs projecting.
